Claims. (Cl. 160-91) My invention relates to an improvement in windowconstruction, wherein it is desired to provide a combination storm andscreen window construction.

One of the usual difficulties in owning a home in the colder regions ofthe country lies in employing storm windows during the cold seasons ofthe year and in applying screens during the warmer portions of the year.Storm windows and screens are normally of a size to enclose the entirewindow and are thus awkward to apply and remove. This is particularlytrue in the case of storm windows, as the size of these storm windowsmakes them heavy and hard to handle.

'This is doubly true if there is even a slight wind,

due to the area of the windows.

It would often be of advantage to have storm windows both during thewarm seasons of the year and the cold seasons. During the colderportions of the year storm windows serve to'restrict the heat lossthrough the windows. In the warmer seasons of the year storm windowscould also'restrict the entrance of heat into the house.

In order to provide proper ventilation, particularly in the summer time,it is desirable that the windows be easily opened. Also in the summertime, it is almost essential that the window opening be protected by ascreen.

It is the object of the present invention to provide a window equippedwith two sets of slidable sashes, one of which is positioned internallyof the other. In combination with the outer set of sashes, I provide ascreen which fits in the area beneath the uppermost sash of the outerpair and the bottom of the window frame. Due to the fact that the outersashes may slide, it is easily possible to raise the lower sash of theouter pair so that ventilation may be easily obtained through the screenwhen the lower sash of the inner pair is raised. At the same time,however, when the lower sash of the outer pair is in lowered position,the window frame is equipped with a storm window which will assist inlimiting the passage of heat. A

An object of the present invention lies in the provision of a stormwindow comprising upper and lower sashes positioned parallel to the mainupper and lower sashes of the window frame and which may be operatedindividually and independently. As a result either the upper or lowersash of the inner set of sashes may be operated at will, while the outersashes provide a storm window therefor. At the same time, however,either outer sash may also be independently operated when desired toprovide any desired degree of ventilation.

A further feature of the present invention lies in the fact that thescreen and the uppermost sash of the storm window are in superimposedrelation. The screen is removably supported in place and may be detachedwhen desired. When the screen has been removed the outer sash of thestorm window may also be readily removed by merely sliding this sashdownwardly. Thus the screen and one-half of the storm window may bereadily removed, and the remaining sashes may be easily manipulated inorder to wash the same. Alternatively by removing the screen all of thesurfaces of all of the windows may be cleaned if it is so desired.

A further feature of the present invention lies in the provision of a,double sash storm window and in the provision of a screen which normallyis located in the path of movement of one of the sashes of the stormwindow. Thus the screen normally locks one oi' the sashes in positionand no special locking apparatus or weights are required in order tohold the storm window sashes in the desired position.

A further feature of the present invention lies in the provision of ascreen which normally ts tightly between the lower edge of a stormwindow sash and the lower portion of the window frame. This screen isslidably and pivotally supported in such a manner that when it isdesired to pivot the screen outwardly, the upper edge of the screendrops a suicient distance to permit the screen to pivot freely. In otherwords, the screen moves out of engagement with the adjacent storm windowsash as it pivots.

These and other objects and novel features of my invention will be moreclearly and fully set forth in the following specification and claims:

In the drawings forming a part o'i my specication:

Figure 1 is a vertical section through my window showing theconstruction thereof.

Figure 2 is a view similar to Figure 1, illustrating the storm window inopen position.

Figure 3 is a perspective view of a portion of the track or slides inwhich the storm window sashes and screen are located.

Figure 4 is a view similar to Figure 3, showing a portion of the trackopposite to the portion shown in Figure 3.

Figure 5 is a detail View of the screen.

.Figure 6 is a sectional view of a modified form of channel strip.

The window A includes a. window frame I0 of any suitable type to whichhas been applied upper and lower storm window sashes. The frame I0includes a head jamb II, side jambs I2 and a sill I3. A window stop I4extends along the vertical sides of the side jambs I2 and across the topof the window, forming a channel I5 for the lower window sash I6 betweenthe window stop I4 and the parting strip Il. A second groove or channelI9 is provided for the upper window sash 20 between the parting stop Iland the opposed of an upper portion channels 2|. These channels 2| arenot normally provided on a window frame and take the place oi' the usualwindow stop which forms the outer portion of the sliding groove i9 forthe upper window sash. l

The channels 2| are merely strips of metal. or otherV suitable material,channel-shaped in cross section as best seen in Figures 3 and 4 of thedrawings. These channels 2| are secured in place with the inner flangethereof in contact with the outer surface of the upper window sash 20.The

achannels extend from top to lbottom of the window frame opening betweenthe sill i3 and the head jamb Ii, and are held in place by any suitablemeans, such as by nails orrscrews 22. f

It is important to note that the lower storm window sash 23 is in placebetween the opposed channels 2| at the time these channels are insertedin the frame. Alternatively one of the channels 2| may be secured inplace, the corresponding edge of the lower storm window sash 23 may beembraced therein, the opposite channel 2| may thenbe inserted to enclosethe opposite edge of the storm window sash 23, and the storm window maythen be pivoted into the frame, moving the channel 2| into properposition against the outer surface of the window sash 2o. The channels2| form a sliding channel for the lower storm sash 23 so that this sash23 may be moved from lowered position shown in Figure 1 to elevatedposition shown in Figure 2.

A second channel is provided externally of the channel 2|. This outerchannel may be formed by an angle iron strip 24 composed of a baseilange 25 and a right angular flange 28 connected thereto. The iiange 26isarranged parallel to the outer ange of the channel 2|. The outerchannel is thus formed by the outer ilange of the channel 2|, the -baseilange 25 and the ilange 26. Channel shaped strips, similar to thechannels 2| may be used if desired in place of the angles 24, but theangle strips are preferred.

An angle iron strip 21 is secured to the under surface of the head lambThe ends of the angle strip 21 adjacent the side jambs I2 are providedwith mitered corners to cooperate with similar mitered corners on theangie members 24.

As the angle strips 24- extend` from the top of the frame only aboutone-half of the distance to the sill I3, these strips may be fullyattached bcfore the upper storm window sash 29 is inserted therein.After the angle strips 24 are attached,

.the upper storm windowsash 29 is inserted in the channel thus formedfrom the bottom, and moved upwardly into the position shown in. Figures1 and 2 of the drawings. The screen 3U illls the space between the sidejambs i2, the lower edge 3| of the storm window sash 29, and the silli3. The screen 30 may be formed in any suitable way, comprising a frame32 and a screen `element 33 supported thereby.

The screen 30 is constructed as best illustrated in Figure of thedrawings with a pair of oppositely projecting pivots 34 and 35projecting from opposite sides thereof. These pins 34 and 35 aredesigned to maintain the upper portion of the screen within the windowframe l0. The lower edge of the screen is illustrated as being held inplace by friction. Any suitable hook or other fastening means maybeprovided to hold the screen 30 in its proper position.

The lower extremity or one of the strips 24 is constructed as bestillustrated in Figure 3 of the drawings. A portion of the ange 25 is outawa-y from the remainder of this flange, adjacent this 4 lowerextremity. This strip` 24 is held in place in any suitable means, suchas by the nails or screws 31. A vertical slot 39 having an outwardlyturned lower end is provided in the lower extremity of the angle stripbelow the level of the lower edge 3| of the upper storm window sash 29.This slot 39 is provided to accommodate the pivot pin 35, which mayslide vertically and outwardly therein. The pin 35 is inserted axiallyinto the slot and when once in place restricts the movement of thescreen 30.

The opposite end 40 of the other angle strip 24 is provided with alowerportion'4l of the flange 25 turned rearwardly to overlie an edge of theside jamb |2. This lower portion 40 is provided with a vertical slot 42therein having an outwardly turned lower end, said slot being in opposedrelation to the slot 39 and below the level of the lower edge 3| of theupper storm window sash 29. A transverse slot 43 is provided in theflange 26 of the angle and extending into the portion 4| of the flange25 thereof. Thus when the pin 35 is inserted in the slot 39, the0pposite pin 34 may be inserted through the slot 43 into the verticalslot 42.

The transverse slot 43 is positioned intermediate the upper and lowerends of the slot 42 so that the pin 34 will not be in registry with thisslot in either extreme position of the screen 30. When the screen is inits normal closed position, as 1llustrated in Figure 1 of the drawings,the pin 34 will be in the upper portion of the slot 42 above the levelof the slot 43. When the lower edge of the screen 30 is pushed outwardlyso that the screen assumes the position illustrated in dotted outline inFigure 2 of the drawings, the pin 34 will be engaged in the lowerextremity of the slot 42. Thus it is necessary to elevate the screen toits mid-position before the same may be removed, thus eliminating thechance that the screen will become accidentally disengaged.

"The lower and upper window sashes I6 and 23, as well as the lower andupper storm window sashes 23 and 29 are provided with panes of glasstherein in the conventional manner. When the window is in the positionillustrated in Figure 1 of the drawings, a storm window is provided,acting as a double insulation. When ventilation is desired, the lowerstorm sash 23 may be raised into the position illustrated in Figure 2,and held in this position by any suitable means. When in this elevatedposition the window serves the pur.- pose of providing a screen windowwhich may provide the desired amount of ventilation. The storm sash 23may be held in any intermediate position as desired to provide arestricted amount of circulation.

In place of the separate channels 2| and angle strips 24, these twoelements can be combined, as best shown in Figure 6 of the drawings.This View shows the two channels formed of a single piece of material.The ilange 44, base iiange 45, and intermediate ange 46 form the innerchannel for the lower storm sash, taking the place of a channel 2|. Theintermediate flange 41, base flange 49, and outer flange 50 take theplace of an angle strip 24. The section is taken in the upper portion ofthe strip, as the outer channel, formed by flanges 41, 49, and 50, arecut away in the lower portions of the frame in much the manneipreviouslydescribed in connection with the strips 24.
